-
Algebraic Identities:
- a² = 2ab + b² = (ab)²
- x² - a² = (x + a)(x - a)
-
Trigonometric Identities:
- sin x
- csc(-x) = -csc(x)
- cot(-x) = -cot(x)
- sech(x) = (e⁻ˣ + eˣ)/2
- coth²(z) = csch²(z) - 1
- various trigonometric formulas involving sin, cos, tan, cot, sec, csc, sinh, cosh, tanh, coth, sech, csch
-
Other Formulas:
- xₙ₊₁ = (xₙ/2)(3 - a xₙ²)
- Various formulas related to series and sequences (Sn, aₙ, etc.)
- ~Vx[~p(x)] =∃x[p(x)]
- ~(p∧q) = ~p∨~q
- Various formulas related to sets, logic, and discrete math
Mathematical Logic
-
Logical Connectives:
- And (Conjunction): ∧ (p∧q)
- Or (Disjunction): ∨ (pvq)
- If...then (Implication): → (p→q)
- If and only if (Biconditional): ↔ (p↔q)
- Not (Negation): ~ (~p)
-
Truth Tables: Truth tables for all the logical connectives are presented, showing the output based on input combination
-
Types of Statements:
- Tautology (always true)
- Contradiction (always false)
- Contingency (neither always true nor always false)
-
Converse, Contrapositive, Inverse:
- Converse (q→p)
- Contrapositive (~q→~p)
- Inverse (~p→~q)
-
Negation of Statements:
- ~(p∨q) = ~p∧~q
- ~(p∧q) = ~p∨~q
- ~(p→q) = p∧~q
-
Logical Equivalence and Duality:
- Duals/Equivalent statements involving the substitution of ∧ and ∨ (and vice-versa)
-
Mathematical Logic Application to Switching Circuits:
- AND, OR, truth tables, and their relation to switches and circuits explained
-
Sets and Logic Various formulas and explanations about sets, and logic presented in the document, including different types of propositions, compound statements, and logical connective notation.
